G'day punters,

I was hoping someone could tell me what size and thread the drain plugs are for sierra gear boxes?
I need an answer within the hour if you can help...

Gearbox fill and drain bungs are M16 thread.

Diff Fill is M20 thread, drain is M16.

In another post, someone asked what alternatives there were to the 10mm square drive found in the Drain and Fill plugs on Widetrack Sierras. Sorry I can't find that thread, but this one will do (maybe?)

All Suzuki 4wd gearbox (and Diff Drain and Sierra Transfer case) threads are the same M16 tapered thread, but various models had different "Heads" on the threads to remove them.

The LJ50 and 80 had a 14mm square drive male that was used with a 14mm spanner, Suzuki P/No 09246-16003

The early SJ410 had a 10mm Allen Key Hex, P/No 09246-16004

Late SJ410 had a 22mm Hex head with aluminium gasket (Ring spanner or socket), P/No 29446-80050

SJ50 and SJ70 had the 10mm Square drive that fill with mud and rounds off your 3/8" adapter, P/No 09246-16009, or 09246-16010 with magnet.

As the earlier numbers supercede to the later ones, the early ones may no longer be availble from Suzuki, so contact your Suzuki Stealership to confirm, Oops I meant Dealership.

Jimny has the same bastard set up, a proper spanner with the 10mm square drive can be bought for around $20-30. I rooted the filler plug up and had to heat and ezy-out the thing. Got away with 5 out of 6 with the 3/8 drive, but #6 made up for it

Is there a hex nut available for the Sierra diffs? Part number? Mine are rooted.

Yes, there is a Hex head version. The part number I gave is for the gearbox and Transfer plugs.They also require an Aluminium gasket washer, P/No 29958-80050. These are most commonly seen on the "1.0lt transfer case with switch".

The Hex Diff fill plug is 09247-20001 and alu washer 09168-20001. Check with Suzuki though. They may no longer be available new.

Thread mine here but does anyone have more info on the 20mm thread type/size for the diff filler plug. I'm looking to retap mine and all I know is that it's 20mm. If anyone knows the thread depth/pitch/type or what ever is needed to buy the correct tap the info would be greatly appreciated
